To (bl/- xix/tom 112% may concern:

Be it known that 1, JOHN Mitiioimn, a citizen oi the United States, re at Springfield, in the county of Clark and State of Ohio; haye invented certain new an. useful l'mpr ovements in tion, reference being had therein to the no companying drawings.

This invention relates to separable springhinges, and has for its object to provide a spring-hinge designed for use more particu-- larly in connection with screen-doors, althrough capable of use in other connections, which hinge is so constructed that the removal and replacing of the doo.1'.ina .ybc road ily accomplished, the hinges which support the same being separable and the removal of thedoor merely requiring-the removal of the hinge-pintles, the spring romainii'ig in position on one of the members and requiring no special provision for holding it in proper pr.- sitionv To these ends my invention consists in certain novel features, which 1 will now proceed to describe and will then particularly point out in the claims.

In the accompanying (.lI'tL'WlIlgS, Figure l is an elevation oi a structure embodying my invention .in one form, the same being shown partly broken away. Fig. 2 is a detail sec-f tional View taken on the line of Fig. 1 and looking in the direction of the arrows. Fig. 3 is a detail perspective view showing the two main hinge ineml'iers slightly separated and the auxiliaiy hinge member in position on one of the main members, and .liig. 4 is a detail sectional view illustrating a modification.

In the said drawings, 1 indicates a door, shown in the door, and 2 the doorjamb, to which the door is hinged. in the present instance I have shown only one of the hinges, the same being composed of two main members 3 and i and anauxiliary member Eaoh main member comprises a baseb and lugs 7, which latter are arranged at right angles to the base, the lugs of the two main members being rranged to overlap and being and which is pl'OVidQCl with a head 9 to hold it in position and facilitate its removal. The base portion o of the main members serves to secure the same respectivelyto the (lo-1 and jainb, said bases being provided with aperpreserit instance as a screenapertured for the pas sage ofthe hinge-pintle 3, which is reiiiovahle l also Separablc Spring-- Hinges, o'f wlnch the foliowmg is a specihom 1 hinge are asse tures lttfor the passage ol screws 11 or other suitable fastening means. The 1 auxiliary member 5 also comprises a base 12 and lugs- 'l 3, by means of which said aiixiliary member pivoted on the pintlc 8. .ln my prel'ei'rcd construction, which that shown in figs. 1 and 2, the lugs 13 are pro ided with sleeves 14 at their ends, n hich. latter receive the pintlc 8, said sleeves also extending into. the apertures of the lugs 7 of the mainhii'ige 6 5 member 3, thereby serving to pivotally connect the auxiliary member to one of the main members.

15 indicates the spring, whicl around the pintle and around the sleevesM, one of the ends ol said spring (indicated at 16) bearing upon the hinge member 3, to .vhi'c'h.

i is coiled .the auxiliar member .is ivoted, while the other end of said spring (indicated upon the auxiliary member.

The bases of the members 3 usual, ilush with each other shown in Fig".

at 1.7) bears and l are, as at the back, as 2, and when the parts of the mbled the auxiliary member bears upon the base of the member 4, to So which it is not pivoted was to transmit t0 said member the pnissurefof thesp'ring In order to prevent displacement era-1e spring and auxiliary member when the main hinge members are separated, the hinge member 3, 65 to which the auxiliary incmberis pivoted, is provided with a suitable stop to limit the movement of the auxiliary member under the influence of the spring. I prefer to c011- strnct "this stop in the manner, shown, in o wh ch the member 3zis provided with a projection in the form of a flange 18, formed by turning outward the inner edge of the base 6 thereof, the edge of the base 12 of the auxilk iary member 5 abutting against sex; flange, 5 as shown in Fig. H it will be seen that'wheii the parts are asseiiihh-d \hc hinge acts as an ordinary springhinge, the spring acting directly on the main member to which the auxiliary member is w pivoted and indirectly on the other main member through the auxiliary member, which pressed against it by the spriiw.

.Whon it is desired to remove the door, it 18 only necessary toremove the pintles of the hinges, whereupon the main hinge iiici'nbers separate in the manner indicated in Fig.

v. u J, i'rom which, however, the spring has been j omitted for the sake of clearness. When thus separated, the member 4 remains atiw 1-5 removalor insertion 'of the pintle.

to whereupon the pintle is inserted and the No special pro--' hinge is again operative.

' vision for holding the spring is requiredeither in separating or uniting the parts of the hinge, and al that is necessary is the mere The sto holds the auxiliary member in a position sucli that the two main members may be brought together so as to cause their pivot-lugs to 3 register Without compressing the spring, the

1 auxiliary member being so positioned when the mam members are separated that it comes into arallelism with the main member on whiz it bears when m operation upon the brin ing tegether of the-two main members wit theirlijases in the same plane and their pivot-apertures registering. Obviously theinvention is applicable to.

other types of spring-hinges than that illustrated in Figs. 1', 2, and 3 of the'drawirigs,

and in Fig. 4 of the drawings I have shown the invention as applied to -a' wellknown type of hinge in which the member 19, corresponding with the'member '3 of the con- ,struction alreadyd'escribed, has its lugs 20 connected by a continuous sleeve 21, through which the pintle 22 passes. The auxiliary member 23 has its lugs 24 pivoted on this sleeve, whilethe other main hinge member 25 has its lugs 26 arranged outside of the lugs p 20 of the main'member 19'. a The spring 27 is coiledaround the sleeve 21, one end bearing a ainst the member 19, as indicated at 28, while the other end bears against the auxiljary member 23, as indicated at 29. It is 45' ;al'sd' obvious that the base of the auxiliary imember m'ay be of any suitable size and shape, and in the-construction illustrated in Figs. 1, 2, and 3 I have shown it as beingin.

the form of-a strip merely sufficient in size to so have a proper bearing upon themain hinge member to which it is not pivoted, wh le 1n Fig. 4 I have shown it as of dimensions equalto those of the said main hinge member, but centrally cutaway, so as to giveaccess to the screws which fasten said main member in position.- I wish desire to be limited to the exact detailsof construction shown and described, for obvi- 0115 modifications will occur to a person skilled in the art. Having thus fully described my invention, What I claim as new, and desire to secure by Letters Patent, is'

'65 1. A, separable spring-hinge comprising it to be understood that I do not- .two main members for attachment to the door and jamb respectively, and a removable pintle connecting the same, in combination with a spring supported by one of said mem bers, and an auxiliary member pivoted to said spring-supporting main member and bearing against the ot er main member, the spring acting on said auxiliary member and on the main member to which it is pivoted, substantially as described.

.2, Aseparable spring-hinge comprising two main members for attachment to the door and jamb respectively, and a removable -pintle connecting the same, in combination with a spring supported by one of said members, and an' auxiliary member pivoted to said spring-supporting main member and bearing against the other main member, the spring acting on said auxiliary member and -on the main member to which it is pivoted,

said last-mentioned main member being provided With a stop to limit the movement of .the auxiliary member, substantially as described.

3. A separable spring-hinge comprising -two main members for attachment to the door and jamb respectively, said main mom-- bers being provided with overlapping aper tured pivot-lugs, in combination with an auxiliary memberada ted to. bear on one of said mam members ant provided with sleeves engaging the apertures of the pivot-lugs of the other member, a removable i'intle passing through said pivot-lugsand sleeves, and a spring coiled around said sleeves and pinlle and hearing at one end on the auxiliary member, its other end bearing on the main member to which the auxiliary member is thus pivotally connected, substantially as described. e

4. A'separable spring-bin e comprising two main members for attac unent to the door and jamb respectively, said main members being provided with overlapping apertured pivot-lugs, in combination with an auxiliary memberada ted to bear on one of said mam members am provided with sleeves engaging the apertures of the pivot-lugs of the other member, a removable )intlo passing through said pivot-lugs and sleeves, and a spring coiled around said sleeves and pintle' and bearing at one end on the auxiliary member, its other end bearing on the main member to which the auxiliary member is thus pivotally connected, said last-mentioned mai'n member having the inner margin of its base flanged to form a stop for the auxiliarv member, substantially as described.

In testimony whereof I aiiix my signature in presence of two witnesses.
